Measuring wet conditions

Q&A Temperature

I'm trying to measure the temperature in an area, where the Relative Humidity is about 70%, and the air is flowing carry a lot of water drops. Does anyone aware about a probe, specially designed for measuring the temperature in wet environment?

Expert’s answer: Measuring wet conditions

A probe for measuring wet conditions? The answer is simpler than you think. Here’s a hint: Consider the requirements needed for thermal flow meters. Give up? If the humidity of your process causes errors in your temperature monitoring system, then change the sensor orientation.

When you install the sensor head up, the water will run through the sensor and stop at the edge, giving you bad values. However, if you install the sensor head down, then the water will run the other way and give you better readings.

Thus, a small change can have a big effect on your process. However, you do have another option. You could replace your current sensor for a humidity + temperature sensor. While this kind of sensor would support your process best, you’d need to invest a little more. Food for thought.

I want to use the t-mass 150 in my process, but the device won’t have air flow and pressure in the line during a certain period of time. Does this have any effect on our vortex flow meter?
